Abstract

회로는 모터 구동용으로 개시된다. 모터의 스위치 또는 속도를 조정하기 위하여, 회전자의 위치를 가르켜 주는 동일 타입의 몇개의 위상 변화 센서 신호를 발생하는 모터를 몇개의 센서를 연관하는 것이 알려져 있다. 모터의 속도 조정 또는 스위치용 구동 신호는 히스테리시스 비교기에서 상기 신호로부터 유도된다. 실제적 작동에 있어서, 간섭은 센서의 출력부에서 신호상에 과부하한다. 이 간섭은 예를들어 모터 코일 때문이며 계산에 영향을 끼친다. 본 발명의 목적은 모터가 정지했을 때 조차 간섭을 막아줄 수 있는 무제한의 능력을 갖는 타입의 상기 회로를 개발하는 것이다. 상기 목적을 달성하기 위하여 스위칭 장치는 하나 이상의 다용 센서 신호(b,c)의 진폭으로부터 각 비교기(A)에 따른 각 센서 신호(a)용 히스테리시스률을 야기한다. 센서 신호는 양호하게 OR 스테이지(Da,Db,Dc), 비교기(A,B,C)에서 히스테리시스를 제어한 출력 전압에 제공된다. 이 회로는 특히 비디오 레코더의 캡스턴 모터를 스위칭하거나 속도를 조절하는데 적합하다.The circuit is started for motor drive. In order to adjust the speed or switch of the motor, it is known to associate several sensors with a motor which generates several phase change sensor signals of the same type which point to the position of the rotor. The drive signal for the speed adjustment or switch of the motor is derived from the signal in a hysteresis comparator. In practical operation, the interference is overloaded on the signal at the output of the sensor. This interference is, for example, due to the motor coil and affects the calculation. It is an object of the present invention to develop such a circuit of the type having unlimited capacity to prevent interference even when the motor is stopped. To achieve this object, the switching device results in a hysteresis rate for each sensor signal (a) according to each comparator (A) from the amplitude of one or more versatile sensor signals (b, c). The sensor signal is preferably provided to the output voltage which controlled hysteresis in the OR stages Da, Db, and Dc and the comparators A, B and C. This circuit is particularly suitable for switching or regulating the capstan motor of a video recorder.
